INT 7A - Novell NetWare - LOW-LEVEL API - Notes
Note:   this interrupt is used for IPX/SPX access in NetWare versions through
          2.0a; in later versions, you should use INT 2F/AX=7A00h to get an
          entry point even though INT 7A still exists.  For both INT 7A and
          the FAR entry point, BX contains the function number; IPX is
          sometimes called internally with BX bit 15 set.
